We are given dimensions of rectangular bedroom = length of 5m and width 3 m.
Also scale drawing of factor 1/50 of the original dimension.
In order to find the dimensions of scale drawing, we need to multiply scale factor by each dimension.
Therefore, length of the scale drawing is 5 * 1/50 = 1/10 m and
Let us convert it in centimeter now.
1 m = 100 cm
1/10 m = 100 * 1/10 = 10cm.
Width of the scale drawing = 3 * 1/50 = 3/50 m.
100*3/50 = 6 cm.
Therefore, the dimensions of a scale drawing of Elenas bedroom is length 10cm and width 6cm.
Number of dog food packages bought by Byron is 300
Step-by-step explanation:
- Step 1: Given number of bird food packages = b. Find the number of packages for the other animal foods.
Number of hamster food packages = b.
Number of dog food packages = 4b
Number of cat food packages = 1/2 of 4b = 2b
Total food packages = 600
⇒ b + b + 4b + 2b = 600
⇒ 8b = 600
⇒ b = 600/8 = 75
- Step 2: Calculate the amount of dog food
∴ 4b = 4 × 75 = 300

Step-by-step explanation:
Answer:
x/7 - 2 = y
Step-by-step explanation:
To find the inverse of a function, we switch f(x) and x and then solve for f(x). We thus have
x = 7f(x) + 14
subtract 14 from both sides to isolate the f(x) and its coefficient
x - 14 = 7 f(x)
divide both sides by 7 to isolate the f(x)
(x-14)/7 = f(x)
f(x) is synonymous with y here. so we havt
(x-14)/7 = y
This can also be written as
x/7 - 14/7 = y
x/7 - 2 = y
